A new publication from Opto-Electronic Advances; DOI  10.29026/oea.2024.230184  , discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography.   In recent years, the scientific community has witnessed a notable breakthrough in the study and development of electron vortices. Electron vortices are electron beams that carry orbital angular momentum, meaning the electrons move not only in their propagation direction but also rotate in a vortex-like manner. This unique characteristic offers many new physical properties and potential applications, making it a powerful ...

sychologists from Simon Fraser University (SFU) and the University of Sussex have found that people are as hesitant to reach out to an old friend as they are to strike up a conversation with a stranger, even when they had the capacity and desire to do so. The new research is published today in the journal Nature Communications Psychology. Scientific research has shown that social relationships are important to human happiness, and that the greater the number and range of friendships that we engage with, the better our wellbeing. But once relationships are formed, some ...

Even with important strides in addressing health issues across the globe, men have not benefited equally compared to women. Men’s life expectancies have not grown as steadily as women’s over the past few decades, and they are expected to live about five years less than women, according to 2021 global health data from the Human Mortality Database and the United Nations’ World Population Prospects. The discrepancy in life expectancy between men and women persists in places all over the world, and is even growing in other places. At a time when health resources are at a premium and need to be wisely allocated, health professionals ...

For hundreds of millions of years, the oceans have teemed with single-celled organisms called foraminifera, hard-shelled, microscopic creatures at the bottom of the food chain. The fossil record of these primordial specks offers clues into future changes in global biodiversity, related to our warming climate.   Using a high-resolution global dataset of planktonic foraminifera fossils that’s among the richest biological archives available to science, researchers have found that major environmental stress events leading to mass extinctions are reliably preceded by subtle changes in how a biological ...

In a new study in Issues, Dominique J. Baker, an associate professor in the College of Education and Human Development and the Joseph R. Biden, Jr. School of Public Policy & Administration at the University of Delaware, explored the role of student loans on hopeful students striving for college degrees, particularly in STEM.  The cost of attending a public four-year college in the United States has more than doubled since the early 1990s, when inflation is factored in.  Undergraduate student loan debt has become unmanageable for a wide swath of borrowers ...

As computer programming becomes an increasingly valued skill in the workforce, there is a greater need to understand how people learn to code most effectively. Statistics show that up to 50% of students who enroll in introductory programming courses in the United States eventually drop out, suggesting a mismatch between how coding is learned and the way it’s taught. A new study from the University of Washington, published March 5 in Scientific Reports, examines that issue. The researchers recorded electrophysiological brain responses of varyingly skilled programmers as they read ...

Researchers have described the optimal timing for COVID-19 patients to take the antiviral, Paxlovid, to get the most benefit from the treatment, according to a study published April 16 in eLife. The findings suggest that taking Paxlovid three to five days after COVID-19 symptoms emerge may maximise the drug’s ability to reduce viral loads, minimise viral spread and reduce viral rebound. They also indicate that broader use of Paxlovid during this window might be a powerful tool to help curb the spread of the SARS-CoV-2 ...

INDIANAPOLIS—A new $4.8 million grant will support researchers from Indiana University School of Medicine and the Medical Research Council Laboratory of Molecular Biology to study how human neurodegenerative diseases are affected by the misfolding of the protein TDP-43. Misfolding occurs when a protein adopts a conformation which differs from the native one.

Health-monitoring apps can help people manage chronic diseases or stay on track with fitness goals, using nothing more than a smartphone. However, these apps can be slow and energy-inefficient because the vast machine-learning models that power them must be shuttled between a smartphone and a central memory server. Engineers often speed things up using hardware that reduces the need to move so much data back and forth. While these machine-learning accelerators can streamline computation, they are susceptible to attackers who can steal secret ...

A rapidly spreading virus threatens the health of the cacao tree and the dried seeds from which chocolate is made, jeopardizing the global supply of the world’s most popular treat. About 50% of the world’s chocolate originates from cacao trees in the West Africa countries of Ivory Coast and Ghana. The damaging virus is attacking cacao trees in Ghana, resulting in harvest losses of between 15 and 50%. Spread by small insects called mealybugs that eat the leaves, buds and flowers of trees, the cacao swollen shoot virus disease (CSSVD) is among the most damaging threats to the root ingredient of chocolate. “This ...

Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer’s disease, according to a new study published April 9th in the open-access journal PLOS Biology by Kim Hai-Man Chow and colleagues at the Chinese University of Hong Kong. The phenomenon may provide an opportunity to learn more about the neurodegeneration process, and the technique used to make this discovery is readily applicable to other inquiries about unique populations of cells in the brain. Most neurons in the ...
